| So | Nws yog insoluble hauv dej tab sis soluble hauv ntau cov emvents ethanic xws li ethanol, ether, thiab chloroform. |
Tshuaj Tshuaj Muaj Zog
N {- heptane yog cov khoom siv hydrocarbon, uas txhais tau tias nws tsuas muaj ib qho kev sib tw ntawm cov roj ntsha atoms thiab yog qhov ruaj khov nyob rau hauv ib txwm muaj.
Nws tuaj yeem yauv hla kev sib txuam sib txawv hauv lub xub ntiag ntawm cov pa oxygen, ua luam yeeb cov pa roj carbon dioxide thiab dej. Kev ua tiav kev sib txuas sib xyaw yog c7H16+11O2⟶7Co2+8H2O.
Nws tseem tuaj yeem koom nrog kev hloov pauv hloov pauv nrog halogens raws li kev ua ntawm lub teeb lossis cua sov. Piv txwv li, nws tuaj yeem cuam tshuam nrog chlorine los ua chloroheptanes.
Kev siv
Siab
Nws yog dav siv los ua cov kuab tshuaj nyob hauv lub chaw soj nstuam thiab kev lag luam. Nws yog feem ntau siv los yaj tsis- recco li cov roj txhuas xws li cov rog, roj, thiab waxes. Nyob rau hauv cov xim thiab txheej kev lag luam, nws yog siv los ua cov kuab tshuaj rau cov resins thiab cov pigments.
Roj tiv thaiv
Nws yog ib feem ntawm roj av. Lub octane tus naj npawb ntawm n {{{1} eptane yog txhais tau tias yog 0, uas yog siv los ua kev ntsuas cov tshuaj tiv thaiv kev ua tau zoo ntawm roj av. Blending n - Heptane nrog lwm cov roj hydrocarbons tuaj yeem hloov kho lub octane naj npawb roj.
Tshuaj Nruab Nrab Nruab Nrab
Nws yog siv nyob rau hauv synthesis ntawm ntau cov organic sib xyaw. Piv txwv li, nws tuaj yeem siv los npaj hepene los ntawm dehydrogenation cov tshuaj tiv thaiv, uas yog qhov tseem ceeb hauv nruab nrab rau kev tsim cov plastics thiab lwm yam tshuaj lom neeg.
Kev txiav txim kev nyab xeeb
n - heptane yog cov nplaim taws thiab tuaj yeem ua cov sib xyaw ua ke tawg nrog cua. Nws yuav tsum tau khaws cia thiab siv kom deb ntawm cov cua sov thiab qhib cov nplaim taws.
Kev nqus tau ntawm nws cov vapors tuaj yeem ua rau kev voos rau kev ua pa, kiv taub hau, thiab xeev siab. Ntev lossis siab -}}}}}}}}}}} txoj kev kis tau raug cuam tshuam rau lub hlwb hauv nruab nrab. Yuav tsum muaj cua txaus yog qhov yuav tsum tau thaum siv n - Heptane kom ntseeg tau tias ib puag ncig zoo.
Nws kuj tseem tuaj yeem ua rau tawv nqaij thiab qhov muag khaus raws li kev tiv tauj ncaj qha. Tsim Nyog Cov Khoom Siv Tus Kheej, suav nrog looj tes looj tes thiab kev nyab xeeb, yuav tsum hnav thaum tuav n {1} heptane.
